Interstate 238 (abbreviated I-238) is a short (2.23 mi/3.59 km) Interstate Highway in the San Francisco Bay Area, California, USA. Its western terminus is at I-880 in San Lorenzo and its east end as an Interstate highway is at I-580 in Castro Valley, California. From there it continues south as California State Route 238. I-238 is the only three-digit Interstate that does not have a two-digit "parent"; there is no Interstate 38 (and even if there was, it would go well south of the Bay Area). The number was chosen by Caltrans, who wanted an Interstate for part of CA 238, but at the time there was no available number for a "child" of I-80 (280 to 980 were in use, and there is a CA 180). I-480 is now free thanks to the demolition of the Embarcadero Freeway.
